Clean Air Blog

Last updated: August 2025 This is our third year running this comparison, and it’s become our most-read page. Over that time we’ve seen plenty of models appear and then quietly vanish - often from brands where air purifiers aren’t a core focus. Some disappear entirely, leaving customers with no way to buy replacement filters. That’s why we update this guide each year: to show how purifiers actually perform, which are supported in New Zealand, and how much value they provide. If you’d like to skip ahead, here’s a quick way to jump to the section that matters most to you: Under $300 - Smaller spaces Under $500 - Medium spaces Under $1000 - Larger spaces Over $1000 - Large & commercial spaces Key things to know before comparing purifiers Before we get into the numbers, here are the fundamentals that matter most when choosing a purifier: Clean Air Delivery Rate (CADR):This measures how much clean air a purifier produces (in m³/h). The higher the CADR, the faster and larger a space it can clean. CADR is the single most important metric, far more reliable than “recommended room size” claims, which are often exaggerated. Noise levels (dB):Noise is one of the most practical factors when choosing a purifier. Many brands highlight their lowest “sleep mode” figures, but CADR drops heavily at those speeds. For this guide we’ve used maximum speed noise levels, so comparisons are fair. How to read the numbers: <50 dB - relatively quiet for daytime use, fine in living areas but still very noticeable at night 50–54 dB - modest background noise, upper limit for comfortable indoor environments 55–59 dB - similar to normal conversation, very noticeable if close by 60+ dB - loud and disruptive, best avoided for long periods Price vs performance:The price tag should reflect what the purifier actually delivers. Some big-brand models are expensive but produce less clean air than simpler, better-value units. A quick note on “extra features”When shopping around you’ll see lots of air purifiers with added bells and whistles. Some of these aren’t just unnecessary, they can be unhelpful or even harmful: Ionisers / Negative ion generators - can create ozone and just push particles onto surfaces instead of removing them. These are used to improve CADR figures, without filtering out particulates. UV lights - sound impressive, but don’t get enough contact time to work in fast-moving air. HEPA filters already capture these particles. Auto sensors - often cheap, inaccurate and misleading. We recommend a separate, accurate monitor if you want to track your indoor air properly. 👉 For a full breakdown, see our article: What features matter when choosing an air purifier. How we source and present the data We’ve made every effort to ensure the numbers here are accurate and up to date, but air purifier data can be patchy. Some brands don’t publish CADR or noise levels at all (we’re looking at you Dyson and Shark), or publish only partial figures. Here’s the approach we use, for all purifiers we find available in New Zealand: Manufacturer or retailer specs - when CADR and noise levels are published clearly. EnergyStar database - where CADR is independently verified. Independent tester reviews (e.g. Housefresh, Rtings) when official data isn’t available. If no reliable CADR data can be found, we exclude the model. That’s why this guide shows every purifier in NZ with verifiable performance data. While we’ve double-checked everything, there may still be small differences between sources. Why trust this guide? The internet is full of “Top 10 Air Purifiers” and “Best Purifiers for Dust” lists - even from well-known outlets. Unfortunately, many are built to generate commission, not to give you the best advice. We want to be upfront: yes, we are selling some of the purifiers in this guide. But unlike affiliate-driven lists, our business depends on you being satisfied years down the track. That means filters being available, performance matching the claims, and you getting genuine value. Why you can’t trust every “Best Of” list To show what we mean: in 2024, the NZ Herald published their “Best Air Purifiers in New Zealand” picks. The problems? Many. It was clear this was written by someone (or AI) with no knowledge of air purifiers. They included models with poor clean air performance, no filters available and unsupported models drop shipped from overseas. Their reason for publishing isn’t to inform you, it’s to earn commission on the products they list. We broke this down in detail here: It's a good reminder that while these lists look authoritative, they don't hold up when you check the numbers. Our aim is different: to compare all models where data exists, show how they stack up, and make it transparent why certain units come out ahead. Comparison Analysis (2025): Now that we’ve outlined the key considerations, let’s step into the results. This updated analysis, conducted in August 2025, covers Smart Air purifiers alongside other well-known brands like Breville, Dyson, Shark, Sunbeam, TruSens, Winix, Xiaomi and more. These are all available from New Zealand retailers including the likes of Briscoes, PB Tech, and Noel Leeming. We researched a total of 65 models, but we could only find reliable CADR and noise data on 59 of these. The others were excluded due to missing or unreliable specifications - as explained earlier, if we can’t source credible data, we don’t include the unit at all. Before diving into the detailed breakdowns, it’s worth noting a pattern you’ll soon see across the charts: price doesn’t always mean better performance. In fact, some of the highest-priced purifiers deliver relatively low CADR, while some of the most affordable units outperform their category. Budget Air Purifiers Under $300 (for smaller spaces, up to ~40m²) This category is aimed at bedrooms, nurseries, and smaller apartments. In 2025, we assessed 12 models in this bracket, from brands such as Fellowes, Breathing Better, Sheffield, Sunbeam, Breville, TruSens, and more. Among these, The Smart Air Sqair is the stand out winner. Its CADR of 315 m³/h is more than 50% higher than the next best competitor in this group. To put that in context, the Sqair is suited for spaces up to around 43m², while the next best options in this price range are only suitable for around 26m² (despite often advertising larger “room sizes”). Noise is another advantage. At 52 dB max, the Sqair runs 7–12 dB quieter than its closest rivals, making it more practical for everyday use. And with no ionisers or gimmicks, it remains a safe choice for households with respiratory concerns or young children. Graph 1: Air purifiers under $300 in NZ (price vs max noise vs CADR). Table 1: Budget Air Purifier Highlights   Brand Model Max CADR  Max Noise Price Smart Air The Sqair 315m³/hr 52dB $299.99 Sunbeam Fresh Protect 193m³/hr 59dB $248.00 Trusens Z2000 190m³/hr 64dB $229.00 Breville The Easy Connect 91m³/hr 60dB $270.00 A striking contrast. While the Sqair comfortably outperforms, the Breville Easy Connect struggles. Despite its $270 price tag, it’s loud (60dB) and only suited for spaces of ~12m². It’s a clear example of how price doesn’t always equal performance Air Purifiers $300 to $500 in New Zealand (for medium spaces, up to ~60m²) In this range we start to see purifiers suited to medium living rooms, apartments, and shared spaces. For 2025 we assessed 14 models in this bracket, from brands including Daikin, Shark, Winix, Breville, Breathing Better, Xiaomi, TruSens and more. This segment brings more competition - but one model stands out. The Smart Air SA600 delivers a CADR of 500 m³/h, making it suitable for spaces of ~60m². It shares the top cleaning power with Xiaomi’s Pro 4, but does so at just 53 dB on maximum. By comparison, the Xiaomi Pro 4 and Xiaomi 4 hit 64 dB and 63 dB respectively, which makes them noticeably louder if run at full capacity. Graph 2: Air Purifiers $300- $500 in NZ (Price vs max noise vs CADR). Table 2: Medium Air Purifier Under $500 Highlights   Brand Model Max CADR  Max Noise Price Smart Air SA600 500m³/hr 53dB $439.99 Xiaomi Pro 4 Smart Air 500m³/hr 64dB $400.00 Xiaomi 4 Smart Air 400m³/hr 63dB $325.00 Shark NeverChage 5 165m³/hr 55dB* $350.00 * Noise level reported between 55–65 dB depending on the source. The Shark NeverChange 5 is widely available in NZ retailers and heavily marketed - but its performance is underwhelming. With a CADR of only ~165 m³/h, it’s below the Sqair running on medium (180 m³/h) and only slightly above the SA600 on low speed (135 m³/h) - except the SA600 achieves that at just 24 dB, compared to the Shark’s 55+ dB. This highlights why sourcing transparent CADR figures matters, and why marketing alone can be misleading. Air Purifiers for larger spaces under $1000 in New Zealand (Up to ~85m²) Now we’re moving into units suited for larger living areas, classrooms, clinics, and open-plan apartments. Prices rise sharply in this category, but as we’ve already seen, cost doesn’t always equal performance. In 2025 we assessed 15 models from brands including Sharp, Daikin, Oransi, Winix, Mitsubishi, Breville, and Dyson. Performance varies widely - some units offer genuine large-space cleaning, while others fall far short despite premium pricing. The standout remains the Smart Air Blast Mini Mk II. With a CADR of 740 m³/h, it’s comfortably the most powerful purifier in this price band. Even more impressive: it achieves this at just 49 dB, making it one of the quietest in the group. This combination of high CADR and low noise sets it apart from the competition. The Oransi Mod HEPA is also worth noting. At 574 m³/h and 49 dB, it doesn’t quite reach the Blast Mini’s output but is still a strong performer for medium–large rooms. Like Smart Air, Oransi avoids ionisers and auto sensors, focusing on straightforward HEPA filtration. By contrast, Dyson’s premium models again show very low performance for the price. The TP07 manages just 153 m³/h, and the HP03 only 113 m³/h, both at a noisy 62 dB. With Dyson not publishing CADR, these figures are drawn from independent testing, where results have consistently been underwhelming. Graph 3: Air purifiers $500 - $999 in New Zealand (price vs max noise vs CADR). Table 3: Large Space Air Purifier Highlights Brand Model Max CADR  Max Noise Price Smart Air Blast Mini Mk II 740m³/hr 49dB $799.99 Oransi Mod Hepa 574m³/hr 49dB $850.00 Mitsubishi ElitePure 508m³/hr 55dB $520.00 Dyson Pure Hot+Cool HP03 113m³/hr 62dB $899.00 The Blast Mini dominates on CADR and noise, providing exceptional value. On the other end, Dyson’s numbers highlight how marketing can mask poor real-world performance. Large & Commercial Air Purifiers over $1000 in New Zealand (Up to ~130m²) This category targets large homes, gyms, clinical settings, and classrooms - places where serious air cleaning power matters. We evaluated 15 models in this price range from brands including IQAir, Trusens, Dyson, Breathing Better, and more. (Note: we excluded ultra-premium units above $10,000 from the graph to keep things readable.) As in previous brackets, cost doesn’t always align with performance - and noise. Many premium models may look impressive but don’t add up in real-world use. The Smart Air Blast Mk II remains the standout. At 950 m³/h CADR and a quiet 43 dB, it's the most powerful and one of the quietest options across all price categories. It outperforms or matches other high-end units while running significantly quieter. The Trusens Z7000 comes closest in raw CADR at 930 m³/h, but does so at a loud 66 dB, a big trade-off in daily use. The Trusens Z6000 is slightly less powerful (880 m³/h) but still noisy at 63 dB. At the ultra-premium end, IQAir models stand out for their build quality and serious filter packs, including substantial carbon beds in some variants. Units like the HealthPro 250 or GC MultiGas don’t compete on CADR per dollar, but they are trusted for specialist applications where filtration quality (including gases and chemicals) matters. By contrast: Breathing Better X-Large Room: 800 m³/h at 70 dB - very loud for the output. Fellowes AeraMax Pro AM4: 748 m³/h at 68 dB, but costing over $2,000. Dyson’s premium Hot + Cool range: CADR only 239–311 m³/h with noise around 62 dB - performance more akin to the Sqair, despite being sold as a premium purifier. Their appeal lies in sleek design and fan/heating features, but in pure cleaning efficiency they lag behind. Graph 4: Air Purifiers $1000+ in New Zealand (price vs max noise vs CADR). Table 4: Large & Commercial Space Air Purifier Over $1000 Highlights Brand Model Max CADR  Max Noise Price Smart Air Blast Mk II 950m³/hr 43dB $1100 Trusens Z7000 930m³/hr 66dB $1830 Trusens Z6000 880m³/hr 63dB $1700 IQAir CleanZone SL 820m³/hr 56dB $11,500 Breathing Better X-Large Room Purifier 800m³/hr 70dB $1499 I-Air Pro Air Healer 600m³/hr 61dB $12,883 Dyson Purifier Hot + Cool 311m³/hr 62dB $1099 Takeaway: In this price bracket, the trend is clear! Most high-CADR units are very loud. The Blast breaks that pattern, combining the best output with surprising quietness. Trusens offers similar airflow but at far higher noise, while IQAir justifies its pricing more through specialist filters and build quality than through raw CADR. Dyson, once again, illustrates how sleek design and multi-function marketing can mask very modest air cleaning performance. Wrapping Up: Our 2025 analysis makes one thing clear: price alone is not a reliable guide to purifier performance. Time and again we’ve seen models marketed as premium struggle to match the cleaning power of more straightforward units, and in many cases they’re also far noisier. Across every price bracket, the purifiers we stock have consistently come out among the top performers, not just on CADR but also on noise. When choosing a purifier, focus on the fundamentals: CADR, noise, HEPA filtration and of course price. If those aren’t right, no amount of flashy features or brand reputation will make up the difference. 👉 Still not sure which model fits your space?

It's hard to beat the aroma of garlic or steak sizzling away on the frypan as it fills your kitchen with flavour. But under those delicious scents lies fine particles called PM2.5, that can travel deep into your lungs and affect your indoor air quality. In a test in a Christchurch apartment in May 2025, cooking on a front burner pushed PM2.5 levels throughout the apartment into the hazardous range, even with the rangehood set to full power. In this article we'll show you exactly how we measured those spikes, how bad it got and how much of a difference using Air Purifiers made. Armed with this information, you can ensure you keep your air clean, whatever you're cooking! Figure 1: Rough Layout of Apartment + Positions of Monitors and Purifiers First Test: Baseline (No Air Cleaning) This experiment actually started accidentally, after noticing the air quality as measured on my QP Pro units was at very concerning levels. It turned out that even at full power, my rangehood barely captured smoke from the front two hobs. This is definitely a bit of a surprise given this is a relatively new apartment.After frying for about 15 minutes, it seemed a little hazy and smokey inside. I checked my air quality monitors in both the lounge and separate bedroom, and both showed very high readings! With PM2.5 counts of over 300 µg/m³, you really want to limit your exposure to this. For perspective, this is about three times higher than the average pollution level in Delhi, and is well into 'hazardous' air quality levels.  If you stop cooking, you immediately remove the PM2.5 source. But on a chilly day with windows closed, those particles can linger for hours. While the rangehood extractor fan was used, it hadn't effectively drawn out the cooking smoke. Being a chilly day, no windows or doors were opened. Here is how the air quality looked over the evening: Figure 2: PM2.5 Readings in Bedroom and Lounge from Cooking Note: PM2.5 to air quality ratings sourced from EPA AQI breakpoints. As you can see, the PM2.5 levels shot up very quickly when the cooking started. For several hours the air quality was at or above unhealthy levels, even lingering at hazardous amounts for awhile! What does this mean? Basically the equivalent of smoking about 1.3 cigarettes! Definitely not something you want to be regularly exposed to. Especially if you have asthma or other breathing sensitivities. Second Test: With Air Purifiers This time, our accidental experiment was repeated with one key tweak, switching on air purifiers when the concentrations peaked. The apartment is well covered on that front, with a Smart Air Sqair in the bedroom and a Smart Air SA600 in the main living/kitchen area.You'll notice from the layout graphic earlier, we've also placed the purifiers away from the air quality monitors. This helps ensure the readings are representative of the actual air quality in the apartment, and not just the air quality around the purifier.Now the big reveal, how much of a difference can the air purifiers make? We allowed the PM2.5 concentrations to reach similar levels to our baseline test, and then turned both purifiers on at their max power settings. Figure 3: PM2.5 Readings in Bedroom and Lounge from Cooking, using Air Purifiers The outcome? In just 30mins, PM2.5 concentrations had dropped by over 90% - this is compared to between 25% and 29% when we didn't use them. Air quality reached the optimal 'Good' level within 45mins in the bedroom and within 1 hour in the main living area!Why are these air purifiers so effective at removing cooking pollutants and smoke? It's all thanks to the combination of HEPA filters and high Clean Air Delivery Rate (CADR).  The HEPA filters on both units are very effective at absorbing harmful particulate matter in the air, such as from frying and smoke. However, a good HEPA filter won't do much if the purifier isn't able to send much air through it. With CADRs of 315m³/hr and 500m³/hr respectively, the Sqair and SA600 are able to push significant amounts of polluted air through their filters. This makes them best in class when it comes to how effectively they purify air. As you can see, we can back this claim up with real data! Smart Air Sqair Smart Air SA600 Stylish, powerful and quiet at a great price. Perfect for the bedroom, or any space up to 43m². Dual inlets with filters on each side. Serious cleaning power for larger spaces up to 60m², while remaining quiet. Other air quality measures you can take: Ensuring your rangehood is working effectively will certainly help reduce the amount of PM2.5 in the air. Mechanical ventilation i.e. HRV/DVS etc if you have it. This will bring in air from outside or the roof space which should be much less polluted. Finally opening windows and doors to let a breeze through, even if for just a short while will also quickly help lower the amount of pollutants. A note around Gas stoves: This experiment was done with an electric hob. Gas stoves are known to release more PM2.5 as well as Nitrogen Dioxide as they combust - the same concerning compound released by car exhaust fumes (diesel particularly). It's even more important to ensure effective ventilation if you're cooking with gas! Wrapping Up These tests show cooking can spike PM2.5 into hazardous levels, and that a quality HEPA purifier (like our Sqair or SA600) cuts those peaks by over 90% in under 30 minutes. Combine purifiers with a properly positioned rangehood and some fresh-air ventilation, and you’ll keep your home’s air in the “Good” zone, even at dinner time. Want to test this yourself? Grab yourself one of our selection of affordable air quality monitors which can measure PM2.5, such as the QP Pro 2, and gain insights like this into your air quality!

Like many Kiwis, I used to never give a second thought to the air I'm breathing. Our landscape isn't covered in polluting factories or coal plants and we're known for our (relative) clean air. However, after learning more about indoor air quality, I decided to start monitoring the air inside and was surprised by what I discovered! How do you Monitor the Air? While it's not an uncommon thing to do overseas, monitoring air quality is still something not many Kiwis are familiar with. While it's possible to pay professionals to come in and do a detailed report, there is a much easier (and cheaper) way. Enter the Indoor Air Quality Monitor, a device with sensors to measure air quality issues such as PM2.5, CO2, VOCs and more. For the past 2 years I've used a QP Lite, QP Pro and Smart Air CO2 Monitor to keep tabs on the air in my home. With an affordable price, high accuracy and data download ability, they're some of the best options on the market and we're pleased to stock them here at Snap Air. First Surprise: CO2 Levels While Sleeping Like many of us, I took it for granted that sometimes we'll wake up feeling groggy, tired and maybe with a bit of a headache. While there are many possible causes for this, have you ever considered CO2 might be behind it? Bedrooms are small spaces and if you close the door and windows, where does fresh air come from? As we breathe oxygen is converted to CO2 and without ventilation the levels can rise surprisingly fast! Especially if you have a partner in the same bedroom. CO2 levels are reported in parts per million, with outdoor air being around 420ppm. Once the air reaches 1000-2000ppm you'll typically experience drowsiness and from 2000-5000ppm headaches and other complaints can occur. I was very surprised to see the levels for my bedroom at night regularly reach over 3000ppm! Once I improved the ventilation, I noticed I'd wake up feeling less groggy and more alert.  Below is an example comparing relatively good ventilation in a bedroom (initially) then poor ventilation later in the week. You can also see just how quickly the CO2 levels drop when ventilation is introduced (opening the door) in the morning! CO2 Concentration Levels: Measured with Smart Air CO2 Monitor Second Surprise: VOC Levels in a New Apartment Having moved into a newly built apartment for a period of time in 2023, I found the 'new building smell' very powerful and I would often get headaches. Unfortunately this is a common experience for many new home owners, as the off gassing from paint, flooring and fabrics etc. produces VOCs like Formaldehyde and Benzene. These can cause symptoms like headaches, respiratory issues, dizziness and throat irritations. There was a sharp increase in average VOC levels reported on my QP Pro after moving into the apartment, compared to an older existing house.  Previously, measurements were around 0.3-0.4 mg of TVOC per m³. In the new building, it was 10 times higher and would be between 3 and 4mg per m³. This puts it in the potentially dangerous threshold. Luckily there is action that can be taken to help reduce these levels. The most effective measure is introducing fresh air by opening doors and/or windows. You can also achieve this with mechanical ventilation. If neither of these options are possible, consider an Air Purifier with Activated Carbon Filter. Here are some readings from the apartment showing the slow rise of VOC levels, then how quickly they get eliminated by opening windows and allowing a breeze through! TVOC Concentrations: Measured by QP Pro Air Quality Monitor Third Surprise: PM2.5 Levels from Vaping While there has been a surge in vaping in recent years, we're still learning about its potential impacts. Having lived with someone who vapes in their room, I've been able to see how it impacts on air quality - especially when ventilation is limited. While it produces a fine mist and sends chemicals into the air, the process of vaporising the liquid also sends particulate matter into the air, including harmful PM2.5. To learn more about PM2.5, see the below video: While I wasn't surprised to see vaping having an impact on air quality, I was surprised at just how high the PM2.5 levels would get - even while in a different room. We've had reports from some of our customers about being impacted by others in their household vaping, which isn't surprising given these results! On the plus side, levels do drop fairly quickly back to normal once the vaping stops. However, peak concentrations ended up at levels you'd see in the most polluted cities in the world, at their absolute worst! The below graph shows the levels of PM2.5 measured from an adjacent room to the one being vaped in. PM2.5 Levels: Measured with QP Pro Air Quality Monitor: Wrapping Up Ready to make your own discoveries in air quality? We've got you covered with accurate and affordable air quality monitors!

Whether it's moving into a new home or doing some DIY renovations, many of us will be familiar with that 'new home smell'. Unfortunately, behind that smell are a number of potentially dangerous chemicals or VOCs such as formaldehyde! For some this may cause headaches, dizziness and other health issues. This brings us to the question: How do you keep yourself safe from these VOCs and can an air purifier help? The good news is there are ways to mitigate these VOCs and the right air purifier can definitely help! Understanding VOCs and Their Sources VOCs are emitted as gases from certain solids or liquids. Common sources in new builds and renovations include: Formaldehyde: Found in building materials like plywood, particleboard, and adhesives. Benzene: Emitted from paints, glues, and cleaning products. Toluene: Present in paints, paint thinners, and adhesives. Health Impacts Exposure to VOCs can cause, amongst other things: Headaches Dizziness Respiratory issues Eye, nose, and throat irritation Monitoring VOC levels with an Air Quality Monitor Using an air quality monitor with a TVOC sensor, like our QP Pro 2 or the Temtop M10 can help you gauge VOC levels in your home. While you won't see levels of each specific chemicals, measuring the VOCs will help give a picture of baseline levels of VOCs in the air and can show the effectiveness of different tactics in reducing VOCs. Effective Strategies for Reducing VOCs Ventilation The most effective way to reduce VOCs is through ventilation: Mechanical Ventilation: Use exhaust fans or air exchangers like HRV systems. Natural Ventilation: Open windows and doors to create a strong cross breeze. Formaldehyde Cookouts These are a way to force more formaldehyde from building materials, furniture etc. in a shorter period of time. Note you should avoid being inside when the cookout is run. Smart Air have written a detailed guide here, however the basic process is: 1. Close windows/doors and increase temperature, through heating or naturally with sunlight. Aim for 30+ degrees if possible. 2. Keep the temperature up for a few hours, ideally 6-8 if possible. 3. When you return, open windows and doors to remove the formaldehyde from the air and return the space to a normal temperature. 4. Repeat this several times  Air Purifiers with Activated Carbon Filters An air purifier with a carbon (VOC) filter can provide additional assistance, especially when ventilation isn't possible. Key Factors to Consider: Amount of Carbon: This determines the amount of VOCs which can be filtered before the filter becomes saturated. Some mesh-style "carbon filters" may last only a few minutes in high VOC environments. Separate Carbon Filter: Allows for easy replacement when needed, as in high VOC situations the Carbon Filter will likely need replacing well before the HEPA filter. Our Recommended Purifiers: Sqair: 120g of activated carbon per filter. SA600: 140g per filter (2 per purifier). Blast Mini: 650g of activated carbon per filter (optional extra). Blast: 1.06kg of activated carbon per filter (optional extra). For additional VOC cleaning power, you can remove the HEPA filter and use multiple carbon filters in our purifiers.   Wrapping Up VOCs are an unfortunate reality in newly built or renovated homes. It's essential to tackle these to maintain good indoor air quality and health. Ventilation, both mechanical and natural, is the most effective strategy. Additionally, using air purifiers with plenty of activated carbon can provide assistance, especially when ventilation is not possible. Formaldehyde Cookouts are an additional tool to help lower the levels of formaldehyde being released.

In New Zealand, many homes struggle with dampness, especially over the colder winter months. This makes dehumidifiers a common household appliance. As awareness about indoor air quality increases, you might naturally consider an air purifier and dehumidifier combo unit. They promise the benefits of both devices in one, but are they truly effective? This blog explores whether these combo units are worthwhile, especially compared to standalone devices. How Air Purifiers and Dehumidifiers Work Air Purifiers Air purifiers are designed to remove pollutants from the air, including dust, pollen, pet dander, mould spores, and other allergens. They work by drawing air through filters, such as HEPA filters, which trap these particles before releasing the cleaned air back into the room. Dehumidifiers Dehumidifiers, on the other hand, are built to reduce moisture levels in the air. They work by drawing in humid air, cooling it to condense the moisture, and then expelling the drier air. This process helps prevent mould growth and reduces dampness in homes. The Promise of Combo Units The idea behind combo units is appealing: one device that handles both air purification and humidity control. Since both appliances deal with air, combining them seems logical. Why get two separate appliances when they can be combined into one? Different Machinery Requirements However, as you can see from the above images, air purifiers and dehumidifiers require very different internal mechanisms to perform their functions. Combining them into a single unit results in a compromise, where neither function is performed as effectively as in standalone units. Performance in Small Spaces In small spaces like bedrooms or laundries, a combo unit might be passable. However, in larger spaces, the limitations become more apparent. Evaluating Combo Units in NZ We did some research on the available combo models in New Zealand. Note we haven't physically tested these, but rely on the figures provided by the manufacturers. The primary metrics we looked at were CADR (Clean Air Delivery Rate) to assess the air purification ability and the daily moisture removal amounts. As a benchmark for the CADR, 200m³/hour makes it suitable for a space of about 27m². Our base model air purifier, the Sqair has a CADR of 315m³/hour and is available for a price of $299.99. Generally moisture removal levels for standalone dehumidifiers start at about 10L/day for low price models and top out at about 40-50L/day for higher end models. High-End Models Philips Series 5000: Priced around $1200, it offers moisture removal of 25L/day and a CADR of 270m³/hour which is close to our Sqair, but comes at a big price tag to achieve this. Breville Smart Dry 2 in 1: Priced at round $600, it removes 21L/day of moisture and has a CADR of 195m³/hour. This is comparable to the Sqair running on medium speed. Budget Models Unfortunately we're extremely limited in our ability to compare other models we've seen by Sheffield, Dimplex & My Genie. None of these provide any information about CADR, but given their small sizes and low dehumidification performance we can't imagine the CADR is suitable for anything except the very smallest of spaces. However a model shared by Sheffield & My Genie was only able to dehumidify 750mL per day, much much lower than any comparable unit! The Case for Standalone Units Given the high cost of a half-decent combo unit, let's look at why standalone units are the best option for most situations. Efficiency and Performance Standalone air purifiers and dehumidifiers are designed specifically for their respective functions, ensuring optimal performance. A dedicated air purifier will have a higher CADR, and a standalone dehumidifier will remove moisture more effectively. Flexibility Using separate units allows you to address specific needs as they arise. For instance, you can run just the air purifier during pollen season or just the dehumidifier during humid months, saving energy and wear on the devices. You also have significantly more options for features, performance ability etc. Another point is a combo unit means there is one point of failure. For example we've seen reviewers unable to find replacement filters, meaning they can't use the air purifier and they're left with an under-performing dehumidifier. Final Thoughts While air purifier and dehumidifier combo units might seem convenient, they often fall short in performance compared to using separate, dedicated units. If you have space for only one device and are willing to spend a considerable amount, a high-end combo unit might suffice for a small area. However, for most situations, investing in separate air purifier and dehumidifier units will provide better air quality and moisture control. While we don't have recommendations for specific dehumidifiers, if you're looking for great value, quiet and powerful air purifiers then check out our range!

Do air purifiers work for mould allergies? Absolutely, air purifiers with HEPA filters can be a game-changer for those with mould allergies. They're great at capturing airborne spores that can trigger allergic reactions. However, it's important to understand that while air purifiers can help manage the allergens in the air, they don't eliminate the source of mould growth. For that, you need to tackle the dampness and humidity that mould thrives on – and a dehumidifier can be instrumental in this battle. Key Points Summary Air purifiers can help with airborne mould spores, reducing allergens in the environment. They cannot remove existing mould growth, which requires physical cleaning and humidity control. Dehumidifiers are essential in preventing mould by maintaining low humidity. Combined air purifier and dehumidifier units exist but may not be as effective as separate appliances. HEPA filters in air purifiers are effective against mould spores, benefiting those with allergies and asthma. Our range features powerful, affordable air purifiers with HEPA filters, perfect for New Zealand homes. Understanding Mould Allergies and Air Purifiers The Battle Against Airborne Spores Air purifiers are designed to filter out the tiny, airborne adversaries that mould spores can be for many of us. A HEPA filter is particularly effective, capturing particles smaller than 0.01 microns. Much smaller than the typical 3 to 40 micron sizes of mould! When Air Purifiers Meet Mould While air purifiers are perfect for cleaning the air, they can't fight mould growth on surfaces. Regular cleaning and controlling room humidity are essential steps in preventing mould from taking hold in your home. Combating Humidity with Dehumidifiers Dehumidifiers play a pivotal role in mould prevention by maintaining an environment that's inhospitable for mould growth. Keeping indoor humidity below 50% can significantly reduce the risk of mould and keep you comfortable. All-in-One: Solution or Compromise? The market offers devices that combine an air purifier and a dehumidifier. While they save space, they often lack the power needed for larger areas, making them suitable only for very small rooms. When it comes to the Air Purifiers on these units, they fall well short of being effective for anything beyond a medium sized bedroom. Because of this, we recommend purchasing standalone units of each. If you're interested in learning more, we've written an article on these combo units. Health Impacts of Mould Mould is not just an aesthetic issue or a homeowner's nuisance; it's a health hazard, particularly for those with allergies or respiratory conditions. Understanding the full scope of its impact can help prioritise why air quality management is essential. The Allergic Reactions to Mould Exposure to mould can trigger a variety of symptoms in sensitive individuals. These may include sneezing, runny or blocked nose, red eyes, and skin rash. For those with mould allergies, these symptoms can be more severe, leading to persistent allergic reactions that can significantly affect quality of life. Mould's Effect on Asthma and Other Respiratory Issues For asthmatics, mould can be particularly harmful. It has the potential to increase the frequency and severity of asthma attacks. Even those without pre-existing conditions may experience respiratory issues in mould-infested environments, such as coughing, wheezing, or shortness of breath. Chronic exposure can even lead to the development of respiratory illnesses in otherwise healthy individuals. Our Powerful, Affordable Solutions Meet Our HEPA Heroes Our air purifiers are equipped with HEPA filters and are designed to be powerful enough for New Zealand's varied home sizes, yet affordable to fit within your budget. With our units, you can ensure that the air in your home stays clean and clear of mould allergens.

With the right combination of air purification and humidity management, you can create a home environment that is safe, healthy, and mould-allergy friendly.

You might have heard about air purifiers with ionisers or negative ion generators claiming to purify the air by releasing negative ions. But have you ever wondered, can these negative ions be harmful? The answer is, unfortunately, yes. Despite the apparent benefits, there's a dark side to these ion-generating purifiers which is often overlooked. In this blog, we dive deep into the unseen hazards associated with negative ion air purification. Key Points Summary: Negative ion air purifiers claim to clean the air by releasing negative ions which cause particles to fall to the ground. These ions can produce ozone, which is harmful to respiratory health. The Ministry of Education in NZ specifically requested air purifiers without ionisers due to the potential risks. Our range of air purifiers avoids negative ions completely, opting for safer, more reliable purification methods. Many air purifiers sold in NZ contain ionisers, sometimes labeled as plasma generators or other names. The Allure of Negative Ions Negative ions are often touted for their apparent ability to improve air quality. They adhere to airborne particles, causing them to become heavy and fall to the ground. This is also used to artificially inflate CADR (Clean Air Delivery Rate) values of some air purifiers. However, the truth behind these claims is more complex and potentially harmful. The Hidden Dangers: Ozone Production Negative ions can lead to the production of ozone. While ozone is certainly helpful up in the atmosphere for the planet, it's also harmful to human health, especially for individuals with respiratory issues. The Ministry of Education in NZ also expressed concerns about this technology, specifically requesting schools do not purchase air purifiers with ionisers for classrooms. The Reality of Negative Ions While there might be potential benefits associated with negative ions, the concentration produced by these purifiers is typically too low to provide any significant advantage. Moreover, the idea of particles falling onto your furniture, bed, or even yourself is quite unsettling. Because of this if you operate the ioniser function, you need to make sure to regularly wipe down and vacuum any surfaces in the area. Instead, it’s far more hygienic and efficient for these particles to be trapped in a HEPA filter. Misleading Marketing Tactics Many air purifiers in NZ carry ionisers, sometimes referred to as plasma generators or by other names. Keep an eye out for any 'special technology' in air purifiers, especially relating to ions. The misleading naming used can lead to unaware consumers purchasing products that might be harmful in the long run. Our Stand on Negative Ion Purification We are firm believers in providing safe, effective air purification solutions. Our range of air purifiers completely avoids the use of negative ions, ensuring a healthier environment for you and your loved ones. Thankfully Smart Air also share the same belief, so nothing in their range includes negative ions. If you already have an air purifier which generates negative ions, we recommend where possible ensuring this feature is turned off at all times. Wrapping Up: When it comes to ensuring clean, safe air, it's essential to choose a purifier that does not pose additional risks. We aim to provide reliable information to help you make an informed decision for the betterment of your indoor air quality.

They can capture up to 99.97% of 0.3 micron sized particles, which are much smaller than common dust particles. When it comes to battling dust, ensuring your air purifier is equipped with a HEPA filter is crucial. Evaluating Air Purifiers for Dust There's probably hundreds of different lists on the internet showing various models of air purifiers which can help reduce dust. So let's make it easier for you! Clean Air Delivery Rate (CADR) When shopping for the best purifiers for dust, considering the Clean Air Delivery Rate (CADR) is the most important factor. CADR indicates the volume of filtered air delivered by an air purifier. The higher the CADR, the more effective it will be in larger spaces. Make sure to compare different models based on their CADR and not just the room size recommendations from manufacturers - as these are often misleading. Noise and Affordability The quiet operation is essential, especially if the purifier will be running in bedrooms or living areas. Getting one which is too loud for you means you've just bought an expensive decoration. Moreover, affordability doesn't always mean compromising on quality. Our guide to choosing an air purifier can help you find a balance between price, performance, and noise levels. Our Top Picks for Dust Reduction Our range of air purifiers is perfectly tailored to meet the demands of a dusty home while ensuring you don't break the bank. With high CADR ratings and low noise levels, they are the go-to choice for creating a fresher living environment in New Zealand homes. Other Dust-Busting Measures Besides investing in a quality air purifier, there are other steps you can take to reduce dust in your home. Regular cleaning, using doormats to capture dirt from shoes, and maintaining your ventilation system can all contribute to a less dusty home. Wrapping Up Reducing dust in your home is a multi-pronged approach. A reliable air purifier with a HEPA filter forms a key pillar of this approach, complemented by regular cleaning and maintenance routines. With cleaner air, your home becomes a more comfortable and healthier place to live.

Air purifiers work to reduce the presence of viruses and bacteria in the air.  The Surprising Risk of Outdoor Pollution New Zealand's picturesque landscapes can be deceiving when it comes to air quality. Construction, vehicle emissions, and fireplaces contribute to outdoor pollution, including the dangerous PM2.5 pollutants, which can infiltrate your home, posing a risk to your little one. Pet Dander and Other Allergens Many families couldn't be without their furry companions, but pets can introduce dander and other allergens into the air. An air purifier can significantly mitigate these allergens, ensuring a fresher environment for your child. Take a look at our article to learn more about how an air purifier can help with pets. The Impact of Air Quality on Children Children, with their still-developing organs and faster breathing rates, are more susceptible to the adverse effects of poor air quality. This article by Smart Air sheds light on how air pollution can affect children even before birth, linking exposure to certain pollutants with birth defects. Air pollution doesn't spare the toddlers and young children either. It has been associated with neurodevelopmental disorders, childhood obesity, reduced lung growth, acute lower respiratory infections (ALRI) like pneumonia, asthma, and even childhood cancers. A staggering fact is that air pollution accounts for 1 in 10 deaths in children under five years old globally. Given these alarming facts, the case for a quality air purifier in your nursery becomes a compelling one. An air purifier equipped with a HEPA filter and a carbon filter can significantly reduce the exposure of your child to these harmful pollutants, providing a safer environment for them to grow and thrive. Choosing the Right Air Purifier Not all air purifiers are created equal, especially when it comes to safeguarding the health of our little ones. We've got an in depth guide here, but here are some crucial factors to consider: No Negative Ions It’s alarming to find a range of air purifiers in New Zealand marketed for use in nurseries that release negative ions. While they might sound harmless or even beneficial, these ions can produce ozone—a gas that’s harmful to the lungs, particularly the still-developing lungs of a child. In New Zealand the negative ion generation 'feature' is often marketed with different names including ionisers, plasma generators and more. HEPA Filters Are Your Friend HEPA filters HEPA filters are the gold standard in air purification, capturing over 99% of 0.3 microns sized particles - the hardest to capture. Ensure that the air purifier you choose has a genuine HEPA filter, and avoid products with "HEPA-like" filters, which are less effective. Consider the Noise and Lights You’ll want an air purifier that operates quietly to ensure your baby can sleep soundly through the night. Similarly, many air purifiers come with bright lights which could disturb your child's sleep. Look for models that operate under 30dB on low and allow you to turn off the lights (or like ours which have no lights!). Price and Performance Investing in a quality air purifier pays off in the long run. Make sure to look at the Clean Air Delivery Rate (CADR) when comparing air purifiers, and not the room sizes recommended by manufacturers as they can be misleading! Our Selection for Your Peace of Mind We’ve curated a range of air purifiers tailored for New Zealand homes, ensuring safety and effectiveness. Our selection of Smart Air purifiers avoids any models that release negative ions, operates at low noise levels and most importantly is affordable!

As parents, we can’t control the outdoor air quality, but we certainly have a say in the air our little ones breathe indoors. Take a step towards creating a safer, cleaner environment for your baby, and breathe easy knowing you’ve made a sensible choice.

Waking up to a stuffy nose, feeling congested, or experiencing exacerbated asthma symptoms can be early signs that the air quality in your bedroom needs improvement. Air purifiers are a proven way to enhance the air we breathe as we snooze. However, while on the search for cleaner air, the last thing anyone wants is a noisy machine buzzing through the night. This piece dives into the essential factors that contribute to making an air purifier both effective in purifying the air and quiet enough to ensure a peaceful night's sleep. Top considerations for your bedroom air purifier: Noise Concerns: A loud air purifier can be a deal-breaker for restful sleep. It's important to find a balance between effective air purification (CADR values) and low noise levels, especially on lower speed settings. Transparency in Performance Metrics: Many manufacturers may not provide clear CADR values at quieter settings or may overestimate the recommended room sizes. Transparency in noise level and CADR metrics is key to make an informed choice. What Does 'Quiet' Really Mean? For undisturbed sleep, experts recommend air purifiers with noise levels below 30dB. Some models, like The Sqair (23dB), SA600 (24dB), and Blast (29dB), fall within this quiet spectrum. Don’t Let the Lights Disturb You: The display lights on air purifiers can be disturbing in a dark room. Opt for simple models with no lights or displays which can switch off to maintain a dark, sleep-conducive environment. The Balancing Act: Noise Levels and Air Purification Efficiency The Noise Factor The tranquility of your bedroom is paramount. While some air purifiers may sound like mini-tornadoes on their max settings, finding a quieter option that doesn't compromise on air purification is key. CADR Values at Quieter Settings Lower settings often equate to quieter operation but may also mean decreased CADR (Clean Air Delivery Rate). It's a tad challenging since many manufacturers often skirt around providing CADR values at these quieter settings. Manufacturers can also be a bit too optimistic with their recommended room sizes. In reality, on lower speed settings, a few of these units might just about manage the air in your wardrobe! Transparency in Performance Metrics We believe in transparency and provide the noise level and CADR of all our products to help you make an informed choice: Model Speed CADR Space cleaned in 20mins Noise The Sqair High 315m³ 42m² 52dB Medium 180m³ 24m² 43dB Low 65m³ 9m² 23dB SA600 High 500m³ 67m² 53dB Medium 260m³ 35m² 39dB Low 135m³ 18m² 24dB Blast Mini High 740m³ 99m² 49dB Medium 450m³ 60m² 43dB Low 340m³ 45m² 36dB Blast High 950m³ 127m² 43dB Medium 680m³ 91m² 37dB Low 450m³ 60m² 29dB  So, How Quiet is 'Quiet'? For peaceful sleep, experts generally recommend noise levels below 30dB. To give you a helping hand: Model Noise level (low) The Sqair 23dB SA600 24dB Blast 29dB However, if you’re a fan of white noise (pun intended) and find it soothing, then you can afford to crank your air purifier up a notch without compromising on sleep quality. Lights Out for Better Sleep One often overlooked aspect of air purifiers in bedrooms is their displays. While many air purifiers come with display lights that can disrupt your sleep, our models are designed with simplicity and effectiveness in mind, devoid of any light-up displays. This ensures nothing comes between you and a peaceful night's sleep, maintaining a dark, serene environment perfect for rest. Wrapping it Up Selecting the right air purifier for your bedroom might take a bit of research, but the rewards — in the form of undisturbed, rejuvenating sleep — are well worth the effort. Ensure you consider noise levels, CADR values at those levels, and the option to have a light-free night. Here’s to breathing easy and sleeping even easier!

Springtime in New Zealand brings new growth, vibrant blossoms and finally a warm change to the chilly air. Unfortunately with this change, it’s also the season of sneezes, itchy eyes, and an endless supply of tissues. If you’ve tried everything from allergy meds to dodging outdoor activities during high pollen days, you might be wondering, can an air purifier help with allergies? Absolutely! Moreover, you might also be curious, what do the best air purifiers for allergy relief have in common? From HEPA filters to high CADR ratings, let’s unravel the common features of top-notch air purifiers that could be your allies in battling allergies. What's Ahead: Understanding Allergens: What causes them and their impact. HEPA Filters: Your frontline defense against airborne allergens. CADR (Clean Air Delivery Rate): Uncovering why this rating matters for effective allergy relief. Top Picks for Allergy Relief: Some top picks well-suited for New Zealand homes. Maintaining Your Air Purifier: Ensuring your device remains an allergy-fighting powerhouse. Extra Tips for Allergy Relief: Steps beyond air purification to keep those allergens at bay. Avoiding Harmful Features: Knowing what to steer clear of when choosing your air purifier. Spring Allergens Spring in NZ brings about allergens for many of us. Understanding common indoor allergens and how they affect your health is the first step toward better allergy management. Common Indoor Allergens Pet dander, pollen, dust mites, and mould spores are among the usual suspects that trigger indoor allergies. Outdoor allergens like pollen, grass etc will often make their way indoors causing allergic reactions. How Allergens Affect Your Health These airborne particles can cause symptoms ranging from sneezing and itchy eyes to more severe respiratory issues, particularly for asthma sufferers. HEPA Filters: Your Defense Against Airborne Allergens HEPA (High Efficiency Particulate Air) filters are proven champions in trapping airborne allergens. How HEPA Filters Trap Allergens HEPA filters are the gold standard for filtering particles. With their tight weave of random fibers, they can capture particles smaller than 0.01 microns. With pollen sizes starting at about 10 microns in diameter, HEPA filters effectively capture these sneeze inducing particles. Different Types of HEPA Filters Though there are variations, the efficacy against allergies across HEPA filter types is quite consistent. An H11 rated filter capturing 95% of particles may sound vastly inferior to an H14 filter with a > 99.995 capture rate. However this is based on the trickiest to capture 0.3 micron sized particle. With pollen and common allergens being much larger in size, what matters more is the CADR of the air purifier. The Significance of CADR (Clean Air Delivery Rate) Understanding CADR helps you choose an air purifier capable of handling the size of your space. CADR Explained A higher CADR indicates a more efficient air purifier that can clean larger volumes of air at a faster rate. This means allergens will be removed from the room faster. Debunking Misleading Room Size Recommendations We've found many manufacturers in New Zealand using very exaggerated room size claims. To avoid this, compare models based on the industry standard CADR for a more accurate representation of their capability. Top Picks for Allergy Relief Finding the right air purifier for your space can significantly improve your allergy symptoms. Choosing an air purifier model While researching you're bound to encounter a multitude of air purifiers and review sites claiming theirs is the "best for allergies,". Don't fall for this marketing and buy an overpriced air purifier! The reality is very simple, ANY air purifier equipped with a HEPA filter and high CADR will serve you well. Our range If you're seeking reliable yet affordable options, check out our air purifier collection. All our models feature HEPA filters, high CADR and low noise levels. Extra Tips for Allergy Relief Some additional measures can further alleviate your allergy symptoms. Housekeeping Measures Using a vacuum cleaner with a HEPA filter and keeping windows closed during high pollen days can help. Night-time Relief for Allergy Sufferers If you find yourself waking up with a stuffy nose, consider placing a quiet air purifier in your bedroom. Typically below 30dB on low will be suitable for most people. Be cautious of models with illuminated displays that might disturb your sleep. Our air purifier collection contains affordable models that are exceptionally quiet, perfect for undisturbed slumber. Avoiding Harmful Features Ionisers: More Harm than Good Despite the claims, ionisers can actually make your allergies worse by releasing ozone, a lung irritant. These are also known as negative ions, and unfortunately a number of models sold in New Zealand contain this potentially harmful feature. The Myth of UV Lights UV lights in air purifiers are generally ineffective in residential settings and add unnecessary costs to your purchase. There is no benefit for allergy sufferers here, just an additional cost. Final Thoughts Investing in an air purifier can be a transformative experience for anyone who suffers from allergies. Remember, the key lies in choosing a device with a HEPA filter and high CADR, while avoiding potentially harmful features. Our air purifier collection makes this choice easier than ever, offering affordability without compromising performance.

Air quality is an essential but often overlooked aspect of our well-being. In New Zealand, many remain unaware of how winter weather can profoundly affect the air we breathe. The Unseen Winter Culprit Winter air pollution in New Zealand is mainly shaped by weather patterns and heating choices. In the colder regions, while less common than previous years, we still see fireplaces being used for warmth. These emit particulate matter; tiny harmful particles into the air we breathe. Even though recently there have been tightened standards as far as emissions from these, they've focused on reducing the larger PM10 particles. The levels of PM2.5 seen in the air however, frequently exceed WHO recommendations. Inversion Layers: A Winter Phenomenon The New Zealand climate significantly influences air quality. In winter, many areas experience cold, still nights. These conditions, along with geographical features like mountains, create 'inversion layers'. This traps cold air and pollutants close to the ground, boosting harmful particle levels. We commonly see these occur in valleys and parts of Canterbury, Otago, Southland and Marlborough. Inversion layers occur when a layer of warm air sits on top of cooler air. This is the reverse of what we normally see where air gets cooler at higher elevations. This "lid" traps pollutants, contributing to higher PM10 and PM2.5 concentrations. PM10 and PM2.5 are particulate matter, or tiny particles in the air. PM10 particles are less than 10 micrometres in diameter, and PM2.5 are smaller, less than 2.5 micrometres. The tiny PM2.5 particles are concerning, as they penetrate deep into the lungs and bloodstream. Health Implications of Poor Air Quality Air quality influences our health. Both PM10 and PM2.5 pose health risks. The smaller PM2.5 particles, which can infiltrate our respiratory system, exacerbate conditions like asthma and COPD and can contribute to heart disease and lung cancer development over time. The World Health Organization states PM2.5 exposure can lead to respiratory and cardiovascular issues, hospital admissions, and mortality from cardiovascular and respiratory diseases and lung cancer. Understanding air quality's link to health is vital, especially for those in colder New Zealand regions, where winter pollution can be harmful. Pollution levels in these areas can reach unhealthy and even very unhealthy levels at times. Measures to Improve Air Quality As we gear up against winter cold, we can also protect ourselves from air pollution. Monitor the Air Quality Understanding the air quality in your area is important. In many countries checking the air quality is as common a task as checking the weather. Monitoring can help us make informed decisions about when to go outside and for how long during poor air quality periods. LAWA (Land Air Water Aotearoa) has a great air quality dashboard which can tell you more about the trends in your area. For live air quality monitoring check out the aqicn website. It can also help to monitor your indoor air, as outdoor pollutants can seep into your home. Personally, I found in my Christchurch home that during cold winter nights the air inside my home would often reach unhealthy levels due to the pollution. Want to check if the same happens to you? We have affordable and high accuracy air quality monitors available on our website. Air Purifiers and Filters Quality air purifiers can remove harmful particulate matter from your home's air. Opt for purifiers with HEPA filters to remove PM2.5 particles. We provide a range of proven, affordable and effective air purifiers from Smart Air. Clean Heating Cleaner heating options can improve air quality. If possible, consider shifting from wood burners to cleaner heat pump options. Wrapping up Awareness is the first step in enhancing our winter air quality. The more we understand, the better we can protect our health and communities. Stay informed, take action, and breathe easier this winter.

Considering the hours we spend at work, maintaining a clean and healthy office environment is a necessity, not a luxury.  One might wonder, can an air purifier make a significant difference in the office? The answer is a resounding yes! Introducing the best office air purifier into your workspace can be a game-changer in enhancing the office air quality, thereby reducing the spread of illnesses like COVID-19 and flu, which is key in ensuring the productivity and well-being of the staff, especially those with allergies or respiratory issues such as asthma.

The Importance of Clean Air in Offices When we think of air pollution, it's easy to picture smog and outdoor emissions. However, the reality is, indoor air pollution often surpasses what we encounter outdoors, particularly in office environments. The very places we spend a large chunk of our days may harbor a cocktail of airborne pollutants, potentially harming our health and dampening our productivity. Mechanical ventilation systems in commercial setups are not always up to the task. Sometimes, they could be circulating, rather than eliminating, pollutants like dust, mould spores, volatile organic compounds (VOCs), and allergens. This circulatory action of pollutants could lead to what is termed 'sick building syndrome,' where occupants experience an array of symptoms like headaches, fatigue, and difficulty concentrating. The impacts can be broad-ranging, affecting not just the health but also the morale and productivity of employees. Research underpins the importance of good air quality on cognitive function and overall productivity. This study highlighted that improved ventilation in office spaces could lead to an 8% boost in employee performance. That's a significant uptick, underscoring the important role of clean air in enhancing work efficiency and creating a healthy environment for staff. The drive towards ensuring clean air in offices isn't just a matter of adhering to health standards; it's about creating a space where employees can thrive, innovate and contribute to their full potential. Hence, aiming for better air quality in New Zealand offices isn't a luxury; it's a necessity which both helps workers and the business.  Choosing the Best Office Air Purifier: Factors to Consider Noise Levels When it comes to offices, a quiet environment is normally best for productivity. It's advisable to opt for air purifiers with noise levels around or below 50dB to ensure that normal communication and concentration aren’t hampered. Budgeting and Value An air purifier is an investment in health. While considering the cost, it's wise to look beyond the initial price. Evaluate the long-term expenses like filter replacement costs, availability, and lifespan. Our air purifiers boast long filter lifespans due to their large surface area, offering you better value for your money. Clean Air Delivery Rate (CADR) CADR is the key factor in determining the effectiveness of an air purifier. While it seems simple enough to look at the recommended room sizes provided by manufacturers, unfortunately these can often be misleading. The best way is to compare the CADR values, which provide a more accurate indication of the air purifier's capability.

Breathing clean air is essential to maintaining our health, and the rising concern of air pollution has made air purifiers a common household item. However, the wide array of models and features can make choosing the right one quite challenging. This article breaks down the crucial features you should look for in an air purifier, such as HEPA filters, activated carbon filters, high Clean Air Delivery Rate (CADR), low noise, and durability. We'll also debunk some gimmicks that are often marketed but may not add value or may even be harmful, like negative ion generators, UV lights, and auto sensors. The Gold Standard: HEPA Filters HEPA filters are the pillar of effective air purification. They can trap microscopic particles smaller than 0.3 microns, including dust, pollen, and pet dander, offering relief for allergy sufferers and those with respiratory issues. It's essential to select an air purifier with a genuine HEPA filter. Neutralise Odours: Activated Carbon Filters   In addition to a HEPA filter, an activated carbon filter can enhance an air purifier's performance. This type of filter excels at trapping and neutralising odors and chemicals, providing a more comprehensive air purification solution when combined with a HEPA filter. Efficiency Matters: High CADR CADR, or Clean Air Delivery Rate, measures an air purifier's efficiency in cleaning air. A high CADR rating indicates an air purifier can filter a large volume of air per hour, which is a key factor to consider when choosing an air purifier. Quiet Operation: Low Noise     The noise level of an air purifier can affect your comfort, especially in quiet spaces like bedrooms. Choose a model with a low noise level, ideally under 55 decibels. Many purifiers offer a "sleep mode" for quieter operation during rest or quiet periods. Durability When investing in an air purifier, durability matters. For commercial-grade units, metal construction is preferable for its longevity. Our Blast and Blast Mini air purifiers are excellent examples of durable, high-quality air purifiers. Features to Be Wary Of While some features enhance an air purifier's functionality, others can be unhelpful or even harmful. Here are some to avoid: Negative Ion Generators/Ionisers These devices produce negative ions that attach to airborne particles, causing them to fall onto surfaces. Do you want these falling on your bed? Unless you're regularly cleaning every surface, we think it's much better if these particles end up in the HEPA filter of your air purifier! The reason these are included, is because it makes the purifier perform better in CADR tests. Particles falling to the ground still counts for these tests. So, if you don't use the ioniser, the CADR will actually be less than what's marketed. Negative ion generators can also produce harmful ozone as a byproduct. Especially concerning for younger ones, elderly or if you suffer from respiratory problems. We've seen these marketed for nurseries of newborn babies in New Zealand, which we consider extremely irresponsible and dangerous. None of our air purifiers include negative ion generators for this reason. UV Lights UV lights are marketed as a way to kill bacteria and viruses in the air, but they can be ineffective against many common allergens and pollutants. While UV lights can kill bacteria and viruses, the main issue is they require time to kill them. If air is quickly passing through the air purifier, the UV light won't have enough time to do its work. Remember as well HEPA filters can normally capture upwards of 99% of these anyway. Auto Sensors Auto sensors, while seemingly convenient, can be wildly inaccurate and may not represent the overall air quality of your space. Instead of relying on these, consider our QP Air Quality Monitors for a precise read on your indoor air quality. An Optional Extra: WiFi     WiFi-enabled air purifiers may seem appealing for those who enjoy remote control or smart home integrations. However, this feature may not be necessary for everyone and can add to the cost. Our range of air purifiers keep things simple and affordable, without WiFi connectivity. However, for those who wish to have this feature, a WiFi-enabled smart plug can be purchased separately at any electronics shop for a reasonable price. Wrapping Up When selecting an air purifier, look beyond the marketing hype and focus on the features that genuinely improve air quality and add value. Always remember that clean, breathable air is the ultimate goal. By making a wise choice, you can ensure a healthier and more comfortable living environment in New Zealand. Choosing the right air purifier can be a daunting task, but we hope this guide has made the process simpler.
